IMPROVEMENT IN TIME-LOCK ATTACHMENTS.

Specification forming part of Letters Patent No. [79,910, dated July 18, 1876; application filed March 16, 1876.

To all whom it may concern:

Be it known that I, HENRY Gaoss, of Cincinnati, Hamilton county, State of Ohio, have invented an Improvement in Time-Lock Attachments, of which the following is a specificat-ion My invention has for its object such a construction of'lock as that, while the time attachment has full powers to define the time at which alone the safe can be opened, it shall have no interfering connection with the operation of the lock-tumblers and bolt, so that the person having knowledge of the combination may, under the commanding influence of burglars, be enabled to adjust the tumblers and throw the bolt to satisfy them that he has proceeded as far as he is capable of going, the safe shall still remain unopened under the controlling influence of the clock.

My invention consists in the provision, in connection with the usual tumblers and bolt, of an extra bolt and dog, the dog being controlled by the clock in such a manner as that when the time is reached for the opening of the safe it is automatically engaged with the extra bolt, the latter then-being moved by and with the bolt proper, and at all other times thrown out, so that the bolt proper has no control over the time-bolt.

Figure l is an elevation of my lock and time attachment in the position in which the timebolt is controlled by the clock. Fig. 2 is a perspective view of the bolts and dogs. Fig.

3 is a perspective view of the inside tumbler ot' the lock. Fig. 4 is a plan of the lock in a position at which the time-bolt is released from the time attachment and connected with the main bolt by the time-dog. Fig. 5 is a perspective view of adog used to secure the time-bolt rigidly when detached from the main bolt.

A and B represent revolving arms of the clock, either or both of which are arranged at the time set, to swing the catch or book C, and

. thus release the time-bolt.

D is the main bolt, or the bolt proper of the lock, and E is the extra bolt or time-bolt. To the bolt D a swinging arm, F, is attached, as shown at d, which carries a pin, a, operating in a slot, 0, of the tumbler-dog G. H is the lockspindle,

which carries the inner tumbler or plate I and the throwing-hook J. Besides this plate I the spindle carries the usual number of tumblers, on which the projection K of the dog G rides until the combination is set, when the dog falls, as usual, into the opening of the plate- I, carrying the arm F down with it, and, by the revolution of the spindle, the hook J is enabled to engage with the hook on arm F, and throw the bolt, the motion being stopped when this bolt is thrown, by the dog-pin g, in the end of the groove t, of the plate I. In the act of throwing, the pin a moves in the slot 0.

When the bolt is locked the notch fot' the arm F engages behind the stud L. The time attachment to the time-bolt E consists, essentially, of the dog M, or its equivalent, connected to the releasing device of the clock in any preferred manner.

I arrange the connection as follows: A frame, N, having a hook, a, to engage with the releasing-hook C at its upper end, and a slot, at, which engages over a pin, h, of the dog M, is pivoted at m to the lock-frame.

YVhen the hook C is released by the clock the frame N falls and carries with it the dog M, which is thus made to engage with the notch e of the time-bolt, so that it is then connected to the main bolt D, the dog M being pivoted to the main bolt. In this condition both bolts are thrown by the single action of the spindle.

In order to secure the bolt E firmly between the times at which it is permitted to be thrown with the main bolt, I pivot a dog, P, to the lock-case, and its end, when the time-lock and main lock are disconnected, engages with the notch e in the timelock bolt, and holds it in place securely.

The lock is ordinarily to be used in connection with a bolt-throwing device of safes, 8tc., which is held locked by the top and bottom edges of the bolts D and E, so that as long as the bolt E remains unthrown no motion of the bolt mechanism of the safe can be made.

I claim- 1. The combination of the bolt D of a permutation lock, an independent locking-bolt, E, a clock-work or time mechanism, and intermediate devices, substantially as herein shown and described, whereby the permutation-lock is left free to lock and unlock and move its bolt D, until the arrival of a predetermined time, without affecting the bolt E, and that upon the arrival of such time a connection is established between the two bolts, so that the lock-bolt will operate the bolt E.

2. The combination of the lock-bolt D, provided With the dog M, the independent bolt E, the locking-dog P, and the time mechanism connected therewith by devices substantially such as shown and described.

3. The combination of the time mechanisms A B, hook 0, frame N, bolts D and E, and dogs M and P, as shown and described.

In testimony of which invention 1 hereunto set my hand.

HENRY GROSS.
